SUNNYVALE, Calif.--(BUSINESS WIRE)--Oct. 12, 1998--

New Low-Cost, Reliable Optical Network Modules Feature

High-Performance Packaging Solution

Oki Semiconductor, a leading manufacturer of advanced integrated circuit solutions for the communications market, today introduced two InGaAsP/InP laser diode modules designed for use in fiber-optic communications and optical networks.

Growing demand for high-speed, low-cost optical fiber networks to support intra-office and short distance datacom applications has created a need for affordable, mass-produced optical laser diode modules.

Leveraging its leadership in high-performance packaging and laser technology, Oki's new optical laser diode modules address the low-cost/high-speed performance trend, supporting data transmission rates up to 622Mb/s. This enables datacom and telecom companies to reduce their overall installation costs, while improving system performance.

These new InGaAsP/InP laser diode modules, the OL3300W and the OL3300N-02, use Oki's highly advanced packaging technology to provide an improved system design by eliminating the need for a condensing lens commonly found in many conventional optical systems.

Utilizing this packaging design provides electronic engineers with optimal laser output power, while simplifying the optical component for an easier, more cost-effective system installation.

"Our advanced packaging technology has enabled us to shorten and automate production cycle time of these devices. This in turn allows us to deliver large-scale production quantities to customers faster and at significantly lower costs," stated Donald Apte, marketing manager for fiber optic products, Oki Semiconductor.

About the Surface Mount Laser Diode Modules

Oki's surface mount optical network modules contain both laser diodes (LD) and photo diodes (PD) and are designed to exhibit high reliability and excellent stability in single-mode fiber operation. Maximum transmission rate for these components is 622 Mb/s (Ol3300N-02).

The OL3300W is a 1.3 micron surface mount mini DIL laser diode module coupled to a single mode fiber with a pigtail. It is designed specifically for use in 155 Mb/s SONET systems and is based on the STM-1 L-1.1/STS-3c standards.

The OL3300N-02 is a 1.3 micron, GaAsP/InP laser diode coupled to a single-mode fiber with a pigtail. This module was designed for use in 622 Mb/s SONET systems and complies with the OC-3/STM-1 I-1, S-1.1 and the OC-12/STM-4 I-4 standards.

Packaging Technology

Conventional optical modules currently utilize a condensing lens to alter the spot size of a light source to match the size of the fiber core. Oki's proprietary packaging technology leverages a 0.5 micron notch on silicon.

This approach eliminates the need for a condensing lens to allow for easier adjustment and alignment, increasing design accuracy and reducing cost. This latest packaging technology is a rugged mini DIL resin-filled flat 8-pin plastic package, which securely contains the optical fiber, thus enabling it to be shock resistant per MIL-STD-883, method 2002.

Pricing and Availability

The OL3300W and the OL3300N-02 are now available in production quantities. These laser diode modules are priced under $100 in small quantities.
